Action Inference by Maximising Evidence: Zero-Shot Imitation from Observation with World Models

1 code implementation NeurIPS 2023 Xingyuan Zhang, Philip Becker-Ehmck, Patrick van der Smagt, Maximilian Karl

Our method is "zero-shot" in the sense that it does not require further training for the world model or online interactions with the environment after given the demonstration.

NeoRL: A Near Real-World Benchmark for Offline Reinforcement Learning

3 code implementations1 Feb 2021 Rongjun Qin, Songyi Gao, Xingyuan Zhang, Zhen Xu, Shengkai Huang, Zewen Li, Weinan Zhang, Yang Yu

We evaluate existing offline RL algorithms on NeoRL and argue that the performance of a policy should also be compared with the deterministic version of the behavior policy, instead of the dataset reward.

Classification-driven Single Image Dehazing

no code implementations21 Nov 2019 Yanting Pei, Yaping Huang, Xingyuan Zhang

The generated images generally have better visual appeal, but not always have better performance for high-level vision tasks, e. g. image classification.

Pixel-wise Regression: 3D Hand Pose Estimation via Spatial-form Representation and Differentiable Decoder

1 code implementation6 May 2019 Xingyuan Zhang, Fuhai Zhang

To use our method, we build a model, in which we design a particular SFR and its correlative DD which divided the 3D joint coordinates into two parts, plane coordinates and depth coordinates and use two modules named Plane Regression (PR) and Depth Regression (DR) to deal with them respectively.

Effects of Image Degradations to CNN-based Image Classification

no code implementations12 Oct 2018 Yanting Pei, Yaping Huang, Qi Zou, Hao Zang, Xingyuan Zhang, Song Wang

In this paper, we empirically study this problem for four kinds of degraded images -- hazy images, underwater images, motion-blurred images and fish-eye images.
